What is an indication for the use of guaifenesin?
Answer Choices:
Correct Answer:
Relief of cough due to minor throat and bronchial irritation
Rationale:
🫁 Guaifenesin is an expectorant used to relieve cough associated with minor upper respiratory infections, such as colds or bronchitis.
🫁 It works by loosening and thinning respiratory secretions, making mucus easier to cough up from the airway.
🫁 This helps convert a dry, non-productive cough into a more productive cough, clearing mucus from the throat and bronchial passages.
🫁 Guaifenesin is typically indicated for “cough due to minor throat and bronchial irritation”, which directly matches the wording in this option.
🫁 Patient teaching usually includes increasing fluid intake to enhance its mucolytic effect and better relieve cough.
“Treatment of bronchial constriction.”
🫁 Bronchial constriction is treated with bronchodilators (e.g., albuterol, theophylline), not with expectorants like guaifenesin.
🫁 Guaifenesin does not dilate bronchi, it only loosens mucus.
“Prevention of blood clots.”
🫁 Prevention of blood clots is the role of anticoagulants (e.g., heparin, warfarin), not guaifenesin.
🫁 Guaifenesin has no effect on coagulation or platelet function.
“Management of allergies.”
🫁 Allergies are typically treated with antihistamines or nasal steroids, not with expectorants.
🫁 Guaifenesin does not block histamine or treat allergic inflammation.
